T0. ctZZ whom, it may concern: Y

Be it known that 1, WILLIAM HEUERMANN, a citizen of the United States,residing at Sedalia, in the county of Pettis and State of Missouri, havemade certain new and useful Improvements in Stoves, of which thefollowing is a specification.

My invention is an improvement in stoves, having for an object, amongothers, to provide a novel construction whereby to secure the maximumheating results by means of a circulation of air and by the introductionof drum sections and tubes, as will be described; and the inventionconsists in certain novel constructions and combinations of parts, aswill be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a stove embodying myinvention. Fig. 2 is a cross-section thereof on about line 2 2 ofFig. 1. Fig. 3is a vertical cross-section on about line 3 3 of Fig. 2,and Fig. tis a detail perspective view of the inner side of one of thehinged drum-sections.

In carrying out my invention I make the stove in two sections, an uppersection A and the lower section B, the latter including the fire-box B,with its grate B and the firedoor B and the damper devices B openingbelow the grate 13 as will be understood from Figs. 1 and 2. The uppersection A is preferably hinged at its rear edge at A to the upper edgeof the section B, so the section A may be turned back on its hinge A toexpose the entire interior of the section B and of the section Awheneverdesired. The section A immediately above the fire-box isprovided with a tube D, extending from front to rear of the section Aand opening at its ends to the atmosphere. This tube D may be made ofany suitable cross-sectional shape, although for convenience inmanufacture it may be preferred to make it round, as shown in Figs. 1,2, and 3. This tube operates to secure good heating results by thecirculation of the air from end to end and through the stove, and italso operates to throw the heat out next to the walls of the stove andadjacent to the inner faces of the opposite side flue-sections,presently described. At its upper end the stove is shown as rounded fromfront to rear and provided at its rear side with the offtake E,-whichmay be in the form of a nipple for the connection of a Stovepipe, asshown. A cross-flue F extends from side to side of the stove, is open atits ends where it abuts the drum-sections, presently described, and isprovided inits lower side, practically in register with the otftake E,with an opening F, controlled by a damper or valve G, having a rod Gextending outside the stove, so the damper G may be opened whenever itis desired to establish direct communication between the interior of thestove and the offtake E in the use of the invention.

The drum-sections II and I are arranged at the opposite sides of thestove and may, if desired, be hinged at one edge at H to the body of thestove and provided at the other edge with a latch H so the drumsectionscan be opened to permit access to the interior of the top section of thestove whenever desired. These drums have a generally circular form andround outwardly from their outer edges toward the center and areprovided at their centers with the conical inwardly-flaredradiating-surfaces hand 4I,which are in alinement and may be connectedat their inner ends by means of a bolt J, as shown. The drum-sections Hand I are substantially alike, being formed to provide a curved fiuehaving the inlet-opening h or t", the discharge-opening 71 or t'registering with the ends of the cross-flue F, said inlet and outletopening being separated by partitions 72, or of, so that the hot air,smoke, 850., entering the openings h and 2" will be forced to travelaround the drum-sections and discharge at 77. or 2' to the ends of thecross-fines F, as will be understood from Figs. 2, 3, and 4 of thedrawings. Openings 77. and i may be provided between the inlet anddischarge openings and cont-rolled by valves k and t to secure a quickerdraft whenever desired, also for cleaning.

' In the operation of my invention it will be noticed the drum-tubeD inadditionto heating the air which passes through it will force the heatout toward the inner sides of the drum-sections II and I, so the heatwill be caused to pass to the inlet-openings of said sections and thenaround the drums and from the dischargempenings thereof to the ends ofthe cross-flue and thence out the ofitake, provided the dampers G, h andt are closed.

If the dampers 72 and are open, the heat will be caused to pass moredirectly to the dischargeopenings h and t", while if the damper G beopen the heat will pass directly from the ofiftake. The conical orfunnelshaped centers of the drum-sections operate in a measure asreflectors for the purpose of throwing out the heat and improving theresults secured in the use of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The improvement in stoves herein described, comprising the lowersection having the fire-box, the upper section hinged to the lowersection, and provided with the drumtube extending from end to end andopening at its ends to the atmosphere, the olftake at the top of theupper section, the cross-flue below the oflftake and extending from sideto side of the stove, and provided with a dam per in line with theoiftake, the circular side or drum sections having the central conicalor funnel-shaped reflectors, and provided with the flues encircling thereflectors and having the discharge-openings in register with the endsof the cross-flue, and the inlet-openings adjacent to thedischarge-openings and the partition crossing the flue between the saidopenings, and the rod connecting the said fluesections at the centersthereof, substantially as set forth.

2. A stove having a flue-tube extending from front to rear and open atits end and arranged to deflect the heat toward the sides of the stove,the drum-sections at the opposite sides of the stove and alongside thedrumtube, and arranged to receive the heat deflected thereby, andprovided with inlet and discharge openings, the cross-flue registeringwith the discharge-openings of the drum-sections, and the offtake,substantially as described.

3. A stove having a flue-tube extending through it and a drum section orsections to which the heat is deflected by the sides of said drum-tube,substantially as described.

4. A stove having the opposite drum-sections, provided with the centralconical or funnel-shaped reflectors and with the fines snrrounding thesame, and having inlet and discharge openings leading to said flue,substantially as described.

5. The combination in a stove, of the stovebody having the cross -flue,and -the olftake communicating therewith, and the opposite drum-sectionshaving the funnel-shaped refiectors, and the fines surrounding the same,and the rod connecting the inner ends of the funnel-shaped reflectors,substantially as set forth.

6. The combination of the stove-body, the fine-tube extending from frontto rear thereof and open at its ends, and the drum-sections at theopposite sides of the stove and on opposite sides of the flue-tube, andhaving the funnel-shaped reflectors extending at their inner ends abovethe flue-tube, and connections between the inner ends of thefunnelshaped reflectors, substantially as set forth.
